[QUOTE="Wado, post: 1174136, member: 42926"] I decided to replace my Remington 700 Tactical Suppressor ready rifle with a nice CZ 527 Kevlar Varmint I bought. I didn't know whether to ask here or on the suppressor forum so I will start here. The 700 has a 16.5" barrel and the CZ is 24" so with my suppressor on that would put it at 30", a bit on the unhandy side. I plan on shooting up to and maybe heavier than sixty grains so I don't want to sacrifice any more velocity than I have to by shortening the barrel prior to threading and in the same time by shortening make the rifle easier to handle. I hope to shoot this rig before I modify it and I would imagine after shortening it and suppressing I will start all over on a load/loads to suit my needs. The rifle has a twist rate of one in nine and that alone I am told is accountable for 1.5% velocity loss so what can I expect from per inch of bore loss, or would the suppressor bore offset the loss of barrel bore to some degree? I don't have a .223 suppressor so it will be passing through a .30 caliber. I realize there is a lot going on when something this heavy is placed at the muzzle, my 700 would shoot 3" low when the suppressor was attached. Any thoughts? I am thinking 20", you can take it off but you sure can't put it back on. [/QUOTE]
